Spiro locks... is there
 

:evilb: A better way to get them in? I checked deck square today, cleaned painted the block and put in the cam bearings and frost plugs. I scribed the gaskets and then measured the top ring to see how far to grind. It's is all good :drink: . I Unshrouded the valves and I then checked the Clarence on the mains .003, and then end play. Torqued it down the Mains and then got really frustrated with the Spiro locks on the pistons, so, i just mocked it up for a woody moment. I am usually not this far behind the curve on anything. I went to the JE website and read the instructions and still struggled. Is there a easier way? Has some motor guru out there that done this and got a system i was using a small right angle o ring pic and a small ignition screwdriver. any suggestions welcome.

Spiro locks are a pain in the azz! No easy way to do it, just bloody finger tips! :D

they are entertaining :D :D stretch them alittle, tiny screwdriver, spin them in :D :D

P.S there are 4 spirolocks per piston ;) learned that a few years ago.. only ran 2 locks per piston in first motor, nothing went wrong :D :D opps

The first ones are always tough. Need not worry they get easier. There even better to take apart.
The older pistons dont even have the notch machined.
What a blast.

I would like to do this the right way. I do not think that installing only one is the correct way if the Manufacturer Says put two per side. But just for entertainment purposes..... how hard did you run your last motor that u only used one per side?

Post #3 and the JE instructions from rmbuilder describe what has worked best for me. I carefully use a very small screwdriver to thread the lock into the piston groove. Like a lot of things, there's a technique to it. Ya don't want to spread the coils too far in the process of installing them. Since you don't reuse them, I've purposely abused a few removing them to see how sensitive they are, They're actually quite forgiving in my opinion. You'll probably find that you get the hang of it about the time you finnish the last piston.
